p. 1475-1498

Benjamin M. Friedman, V. Vance Roley

This paper develops behavioral relationships explaining investors' demands for longterm bonds, using three alternative hypotheses about investors' expectations of future bond prices (yields).

The results also have implications for further aspects of investors' portfolio behavior, including expectations formation, response to inflation, and speed of adjustment.
